GCSE students enjoyed a stunning set of results last night on a day of academic celebration for Suffolk.

But there were concerns yesterday that the A* may have lost its sparkle after a record number of pupils took home top grades.

Results showed the biggest rise in success rates for seven years, with 4% more students achieving five A* to C GCSEs, including English and maths, compared to last year.

More than half of young people reached the acclaimed standard – which has caused concern for those who anticipate an impending clamour for scarcely available jobs.

Graham White, secretary of the Suffolk National Union of Teachers, said: “Clearly the students have worked hard to achieve their A*s and As.

“But I am personally surprised that the number is so high this year and there is certain devaluing among some of the hard work and effort they have put in.”

With so many students shining in their exams, Mr White advised those that really want to stand out from the crowd to look at other ways of enriching their CVs.

He added: “Maybe they could look at gaining more work experience by doing placements, or doing community work with the Scouts, Guides or air cadets.

“They need to sell themselves on their personalities and other skills.”

But Graham Newman, Suffolk’s schools chief, said the increase in success rates illustrated the impact of the county’s strategy to raise attainment.

“Headteachers, teachers and students should be congratulated on their commitment and enthusiasm for learning that has resulted in this tremendous achievement,” he said.

“In times where competition for jobs and further education places is strong gaining good GCSE grades is more important than ever.”

Record results came flooding in yesterday as students ended weeks of nervous waiting.
